Padding

public enum Padding

The padding mode for encryption and decryption. The same padding mode has to be used for encryption and decryption, else the decryption will fail.

  • This indicates that no padding should be used.

    Warning

    If messages are encrypted without padding, the size of the message is disclosed. If that is unintended, use padding instead.

    Declaration

    Swift

    case none

    case padded(blockSize: UInt32)

    Parameters
